PDC (polycrystalline diamond compact) drill bit sustained damage after drilling through hard formation rock. Let’s break this down: Possible Causes of Damage: How to Prevent Future Damage:Bit Selection: Consider using hybrid bits (PDC with impregnated diamond elements) or a tricone bit for hard formations.Optimize Drilling Parameters: Reduce WOB and adjust RPM to avoid excessive wear.Use […]

Pump Jack Well On Fire
The video captures a pump jack well, typically operating under low pressure, suddenly experiencing high-pressure gas from the bottom hole, leading to a blowout and fire. Possible Causes:Gas migration from a deeper zone due to casing or tubing failure.Nearby injection operations increasing pressure unexpectedly.Undected fault movement or gas cap release. What Happens Next?The high-pressure gas […]
Production Logging Tools (PLTs), Unlocking Well Performance
In the oil and gas sector, understanding well behavior is key to optimizing production. Production Logging Tools (PLTs) are specialized instruments used to assess downhole conditions, providing critical insights into fluid movement, reservoir performance, and well integrity. How PLTs Works:PLTs are run into the wellbore using wireline, slickline, or coiled tubing, depending on well conditions. […]
Slip and Cut
In oil well drilling, “slip and cut” refers to a routine maintenance procedure performed on the drilling line to prevent excessive wear and maintain safe operations. The drilling line (a steel wire rope) runs through the crown block and traveling block, supporting the drill string’s weight. Over time, specific sections of the drilling line experience […]
Well Logging Probe: A Key Instrument in Subsurface Evaluation
Function of a Well Logging Probe:A well logging probe is a cylindrical device lowered into a borehole to collect data about rock formations and fluids present underground. It is typically attached to a logging cable, which transmits power and data between the probe and the surface recording system. As the probe moves along the wellbore, […]
Wellhead Installation with Landing Joint Casing
The wellhead is a critical surface component in an oil or gas well, providing structural and pressure control for casing strings and production tubing. When installing a wellhead with a landing joint casing, careful planning and execution are required to ensure a secure and efficient setup. Step-by-step Installation Procedure1.Preparation and InspectionVerify that all wellhead components, […]
High Expansion Bridge Plug (HEX) in Oil and Gas Wells
It is a crucial downhole tool used in the oil and gas industry for zonal isolation, well intervention, and well abandonment operations. This specialized plug is designed to expand significantly, allowing it to pass through narrow restrictions before sealing off larger wellbore diameters. Its versatility and reliability make it a preferred choice for various applications, […]
Shale Shakers
Let’s talk about shale shakers on a drilling rig.This piece of equipment separates cuttings from the drilling fluid. Above the bed rubbers, we install screens. The style screen can vary as well as the size mesh on the screen. After positioning the screens, each screen is individually locked down, making it possible to replace one […]
Sand Plug and Wax Buildup in Wells
In oil and gas wells, sand plugs and wax buildup can obstruct flow and create operational challenges.Sand Plug: This happens when formation sand or proppant from fracturing operations settles in the wellbore, restricting flow. It often occurs in high-rate production wells, horizontal wells, or after shut-ins when fines settle. If severe, it can trap pressure […]
Logging While Drilling (LWD)
LWD is a technique used in oil and gas exploration to collect real-time formation evaluation data while drilling a well. It is an essential part of modern drilling operations, providing valuable information about the subsurface without requiring separate wireline logging runs. LWD involves the use of specialized downhole tools that are integrated into the Bottom […]
